I'm using Mozilla FireFOX 0.8 and i still got the same problem. I used to have it with fileplanet.com on netscape a while ago. Although for a fact refreshing does NOT always fix it, this very thread is beeing shown off screen to me, i refreshed it after reading the post above and it's still the same. I sometimes refresh helps, sometimes it doesn't, although i've found that in a strange way this happens on ls.net pages opened in tabs. It doesn't seem to affect pages in the very first tab.
